| Description: |
International audience ; A search for a β-delayed fission (βDF) decay branch of isomerically pure samples of 178 Augand 178 Aum has been performed at the ISOLDE-CERN facility. Two complementary detectionsystems capable of registering α decays and fission fragments, the ISOLDE Decay Station and theASET (Alpha SETup), were used. Despite very high statistics of produced 178 Au nuclei, no fissionfragments were detected. Upper limits of βDF probabilities of PβDF (178 Aug ) < 1.11(2) × 10−8 andPβDF (178 Aum ) < 9.7(2) × 10−9 were determined. Corresponding lower limits of βDF partial half-lives were deduced as well, and the results are discussed in the context of experimental systematicsof βDF in the neutron-deficient region of the nuclear chart. |
